TC1130
The bit timings for the CAN nodes are derived from the peripheral clock (fCAN) and are
programmable up to a data rate of 1 MBaud. A pair of receive and transmit pins connects
each CAN node to a bus transceiver.
Features
⢠Compliant to ISO 11898.
⢠CAN functionality according to CAN specification V2.0 B active.
⢠Dedicated control registers are provided for each CAN node.
⢠A data transfer rate up to 1 MBaud is supported.
⢠Flexible and powerful message transfer control and error handling capabilities are
implemented.
⢠Advanced CAN bus bit timing analysis and baud rate detection can be performed for
each CAN node via the frame counter.
⢠Full-CAN functionality: A set of 128 message objects can be individually
â allocated (assigned) to any CAN node
â configured as transmit or receive object
â setup to handle frames with 11-bit or 29-bit identifier
â counted or assigned a timestamp via a frame counter
â configured to remote monitoring mode
⢠Advanced Acceptance Filtering:
â Each message object provides an individual acceptance mask to filter incoming
frames.
â A message object can be configured to accept only standard or only extended
frames or to accept both standard and extended frames.
â Message objects can be grouped into 4 priority classes.
â The selection of the message to be transmitted first can be performed on the basis
of frame identifier, IDE bit and RTR bit according to CAN arbitration rules.
⢠Advanced Message Object Functionality:
â Message Objects can be combined to build FIFO message buffers of arbitrary size,
which is only limited by the total number of message objects.
â Message objects can be linked to form a gateway to automatically transfer frames
between 2 different CAN buses. A single gateway can link any two CAN nodes. An
arbitrary number of gateways may be defined.
⢠Advanced Data Management:
â The Message objects are organized in double chained lists.
â List reorganizations may be performed any time, even during full operation of the
CAN nodes.
â A powerful, command driven list controller manages the organization of the list
structure and ensures consistency of the list.
â Message FIFOs are based on the list structure and can easily be scaled in size
during CAN operation.
